Next time you are up against a rude %^&*# receptionist,......do the intimidation stare......keep calm, then look at her badge and ask her name.
Then say you'd like to see her supervisor.

If all else fails, tell them all where they can stick their 'Meet and Greet' and let them know that your team of NT buttbuzz warriors will be making a grand entrance to show them what a MEET and GREET is really all about when dealing with a crew of people racked with PAIN!!!

I'm sorry you are dealing with this. Sometimes we HAVE to be a bit intimidating to get the right kind of respect.
Go above that receptionist's head. She could use a nice refreshing reminder from her higher ups that she is not performing her duties up to par.

I've even used the words "My Attorney will need documentation as to why...."........alot of times THAT will get them to sit up straight and get the ball rolling. NObody wants to have to deal with answering to a legal issue.!

Just some thoughts

I call it 'tough love'
